PAR-K, PENNSYLVANIA, ASSIGNOR TO 1310- CORYORATION OI" PENNSYLVANIA FINISHING WHEEL Application filed January 4, 1929. Serial No. 330,381.

The invention relates to finishing wheels; the object is to provide an improved wheel for finishing the edges of fibrous material, especially the edges of leather 'belts. The device comprises in general the well known wire bufiing wheel or brush clamped between two rigid discs but in accordance with the present invention, so that the peripheries of the discs will extend to or slightly 1o beyond the periphery of the wire brush. The periphery of the brush so clamped is then ground to form an annular peripheral semicircular channel to conform to the required final finished cross-sectional contour of the 15 belt edge.

Referring to the drawings, which illustrate merely by way of example, suitable means for theembodiment of my invention Fig. 1 is a cross-section on line 1, 1 of Fig. 2.

Fig. 2 is a plan vietv with the nut removed and part of one plate and also part of the brush-removed.

Similar numerals refer to similar parts throughout the several views.

The brush 5, used in this device may be of the usual commercial type, consisting of a hub 6 and the wire retaining parts 7 and 8,

from the center of which the wires radiate.

Thisbrush is cIampJed between the two plates washers 11 and 12, all carried on the threaded end of shaft 13 having the shoulder 14 for engaging the outer margin of block or washer 12. A nut'15 is screwed down on the other block or washer 11. These blocks or washers 11 and 12 may of course be made integral with the discs 9 and 10, if desired. The discs 9 and 10 are also concentrically recessed on their inner faces, as at 16 and 17 to receive the hub 6 and other wire securin elements 7 and 8, so that the portions of t e discs at and near their margins may efiectually clamp the two sidesof the brush at the periphery thereof and for some distance therefrom. The brush is clamped at-and near its peri hery as tlghtly as is reasonably practica 1e. This however does. not preventa limited movement of the wires at the periphery, eswtilally in planes .of their rotation. 60 en the rush has been so clamped becorresponding y means of the-blocks ortween the discs 9 and 10, the periphery of the brush is ground so as to form an annular semi-circular channel or groove 18, therein to the required cross-section contour of the belt edge when finished.

"In 0pemtz'0n.--When the leather belt has been roperly or suitably beveled, by cutting or gri ding away the corners of the belt edges, certain filaments or feathers of the fibrous material remain attached to the edge, and the finishing wheel, in accordance with the present invention, serves to remove such adhering parts and gives the belt a smooth clean finish in desired cross-sectional contour. The centrifugal action of the wheel, due to'the peculiar supporting means for the wire strands or bristles, which restrains their lateral spread serves efl'ectively tothrow off the fibers or particles removed from the belt, and thus the periphery of the wheel remains clean and unclogged by such waste material.

The means or restraining said lateral spread of the wire strands, in combination with the grooved periphery of the brush, greatly facilitates the proper finishing of the belt edge. in required contour, and also adds materially to the effective life of the finishing wheel.

What I claim is 1. In a device 9f the a brush having a semi-circular peripheral channel comprising bristle-like strands radiating from a substantially common center, means for clamping both sides of the brush at its periphery to limit the lateral displacement of the said strands, and means for supporting and rotating the same.

2. In a device of the character described, a brush having a circular contour compris- .ing bristle-like strands radiating from a subcommon center, said brush having stantially a grooved peripheral surface, means for clamping both sides of the bristle like strands, said means extending to and beyond the brush periphery to limit the lateral displacement of the said strands, and means for supporting and rotating the same.

3. In a device of the character described, a wire br zsh having a channeled hub and wire bristle-like strands radiating therefron" a character described,

air of discs for clamping the brush thereetween, and-a supporting shaft and aunt threaded thereon for exerting pressure on the discs, the said discs having their periph- 5 eries extending slightly beyond the periphery of the brush.

4. In adevice of the character described, a wire wheel brush having a channeled hub and wire bristle-like strands radiating therefrom, a pair of discs for clamping the brush therebetween, and a supporting shaft and a nut threaded thereon for exerting pressure on the disc, the said discs having their peripheries extending slightly beyond the periphery of the brush and the peripheral surface of the brush formed with a semi-circular channel.

5. In a device of the character described, a wire wheel brush having a'channeled hub and wire retaining devices associated there- I with,wire bristle-like strands radiating therefrom, a pair of discs for clamping the brush therebetween at and adjacent the periphery thereof, having recesses on their inner faces for receiving the hub and wire retaining devices, and a supporting shaft and a nut threaded thereon for exerting pressure on the discs.
